It was centered about 24 kilometers (15 miles) southeast of Granada and about 370 kilometers (230 miles) south of Madrid, Spain's capital.

There was no immediate report of damage or injuries from the temblor. The quake's recorded depth of 616 kilometers -- nearly 400 miles -- means little damage is likely, geophysicist Susan Potter told CNN.

"When an earthquake is deeper, the seismic energy is absorbed by the Earth," Potter said. "So there will be less damage expected in the epicenter area."
